Use one person’s experience as a hypothesis source rather than a market-wide answer
N-of-1 customer research studies one person’s purchase and use in detail. Here it means customer research, distinct from a medical single-case trial.
A detailed account reveals a journey without estimating population shares. Use it to develop hypotheses for investigation with other people.
Choose a person and situation with relevant experience
Choose actual users or evaluators with experience relevant to the question. Do not present one successful client as representative of everyone.
GOV.UK interviews focus on real experiences and examples. Trace a recent purchase and the tasks within it. (GOV.UK: Using in-depth interviews)
Record purchase and use chronologically
Record triggers, information searches, alternatives, purchase, and post-use tasks. Distinguish contemporaneous reasons from later reflection.
Attach statements or actions to interpretations and mark uncertain dates rather than inventing them.
Test with other experiences and a limited offering
Test hypotheses through other interviews and actual tasks. Recurrence alone does not establish a population frequency.
Log product or content revisions. Publish cases with permission, identifying the person’s experience and your work.
For testing interpretations of experience, see developing insights from behaviour and context for practical detail.
